ELEvu-on PLATE Fon Locomonv Dnrvrue PLATES Filed July a.- 1929 agi ATTORNEY Patented Mar. 17, 1931 UNITED STATES PATENT' OFFICE GEORGE R. WILcox AND WILLARD T. MORLEY, or MI'LFORD, UTAH ELEVATOR :PLATE FOR LOCOMOTIVE-DRIVING PLATES Application filed July 8, 1929. Serial No. 376.754.

Our present invention has reference to a lubricating device for journals or other bearings which are lubricated by a solid grease and our object is the provision of a lubricant case designed to be arranged in a well of a journal box and which has its upper face concaved and reticulated, the said case having a solid lubricant therein which is contacted by a spring iniuenced follower in the nature of an arched plate which snugly fits in the case and whose concavity corresponds to that of the concaved face of the case, together with bracing means for the follower and spring means further engaging the bracing means for influencing the follower toward the reticulated arched face of the case so that the entire quantity of lubricant arranged in the case will be fed to the ournal and consequently no waste of lubricant will occur.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a section al view approximately on the line 1 1 of Figure 2, to illustrate our improvement in applied position in the well of a locomotive axle box.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a perspective view of our impiovement.

In the drawings, 1 designates a journal of a locomotive axle which is fitted into a box 2 having the usual brass bearing 3 and the lubricant cellar 4 which is held in place in the usual manner. In the cellar 4 there is arranged for snug fitting a casing 5 that contains therein a solid lubricant 6. The top of the casing 5 is concaved, as at 7, and is either formed of wire mesh or reticulated to provide the same with closely related openings 8. The curvature of the concaved top 7 corresponds to the cross sectional peripheral contour of the journal l that is contacted by the case 5.

but the concaved upper face thereof correspends to the curvature of the top of the case 5. The concaved plate 9 not only affords a bottom for the case 5 but serves as a follower member therein. The follower member 9 may, it will be apparent, be cheaply conf structed, and in order to reinforce and strengthen the said follower member 9 as well as to maintain the same in proper shape l secure to the sides and to the central portion of the bottom of the said follower member the parallel arms 10 and the straight connecting element 11 for said parallel arms, which elements are provided by a metal member. The plate 11 is preferably provided on its under face with clamps 12 that receive therein and hold to the plate the upper convolution of a coil spring 13, the lower convolution of the said curved spring rest-ing on the bottom 14 of the well 4. With our iniprovement it will be apparent that the spring urged follower will cause all of the hard grease `in the case 5 to be forced through the apertures in the concaved top thereof so that the journal 1 will be effectively lubricated. The brass bearing as well as the top of the journal box 2 have alining openings 14 which communicate with a pocket 15 inthe top of the box 2 and which pocket affords a supplemental well for a lubricant or for the lubricant delivered from the case.

We desire to state that we are acquainted' with a lubricant device in which a case similar to that herein set forth is employed and, therefore, make no broad claim to such construction but whatwe do claim is: Y

In combination with a journal box having a lubricant casing provided with a concaved Vperforated top wall to furnish lubricant to a journal of the journal box, a concave-convex plate located within the casing and having the lubricant thereon, a substantially U- shaped member including arm portions and a web portion having the ends of the arm portions secured to opposite edges of said plate and With the web portion engaging the plate intermediate its edges, spaced cleats formed on the Web portion, and a coil spring in the easing for urging said plate towards the top Wall of the casing and having the upper convolution thereof secured to the Web portion by the cleats.

In testimony whereof We aiiix our signatures. y
